Walmart on Wednesday announced it recently completed the nationwide rollout of in-house mobile payments service Walmart Pay, a system promised to one day support third-party digital wallets like Apple Pay.

Walmart plans to get the jump on Black Friday this year with a sales event one week early featuring gift-card-based sales and discounts on a wide range of items, including Apple's new iPad Air 2 and iPhone 6.

Walmart has revealed its sales for Black Friday, and a number of Apple products will see price cuts paired with free gift cards, including iPads and iPhones, while steep discounts will be offered on some Beats products.

Following a move by big box retailer Best Buy, RadioShack and Walmart have announced they too will be slashing prices on Apple's mid-range iPhone, the iPhone 5c, putting the on-contract price for the device at or below $50.

Tonight at midnight, Pacific time, Apple's lower-cost iPhone 5c will become available for preorder, but figuring out just where to get the colorful new iPhone can be a hassle. AppleInsider has put together a round-up of which carriers and retailers will be opening up access for early-adopting consumers.

Just ahead of Apple's expected reveal of the new iPhone, Walmart is looking to attract iPhone trade-ins with a new program announced on Tuesday, a move that will bring the retail giant into competition with not only established services like Gazelle, but also with Apple itself.

Walmart shoppers at more than 200 stores will soon be able to use their iPhones to scan items and pay at self-checkout counters, as the retail giant has announced an expansion of its Scan & Go pilot program.

Best Buy and other retailers have complained to attorneys general in numerous states, accusing Walmart of misleading advertising in the holiday shopping season, including a discount on Apple's iPhone 5.

Walmart, the largest retailer in the U.S., dropped the price of Apple's iPhone 4S with a two-year AT&T contract by as much as $74 at some locations, but the retailer later explained that the reductions were a "pricing error."

In a sign that Apple is rationing supply of the new iPad among third-party resellers, retailer Walmart is only carrying the 16- and 32-gigabyte Wi-Fi models at launch, along with the 64-gigabyte AT&T LTE 4G model.
